Y = 230x + 100<br> Is this proportional or non proportional?

Svet_ta [14]

<h3>Answer: Non proportional</h3>

Proportional equations are of the form y = kx, for some fixed constant k. The k value is the constant of proportionality.

The +100 at the end is why we don't have a proportional equation.

Visually all proportional equations go through the origin, meaning the lines have y intercept of 0. For y = 230x+100, the y intercept is 100.

A markup means the price increases.

$99.50 \times 95\% = 94.525$

$94.525 = 94.53$

$99.50 + 94.53$

$= 194.03$

After the markup the sled costed $194.03.
